King County Sheriff's Office reports say a fight erupted between the brothers, an acquaintance of theirs and Lancaster, which escalated into gunfire from Marque Fluker.

Deputies recognize Marque Fluker as a known member of the Low Profile street gang, which prosecutors describe as a violent group.

Deputies responded to a 911 report of a fight and shooting about 7:41 p.m. at 11656 68th Avenue South. There, a deputy found Lancaster on the ground bleeding, with at least four obvious gunshot wounds, reports say.

The deputy asked Lancaster who shot him as he applied pressure to his wounds. Lancaster replied, "It was Marque Fluker," probable cause documents say.

Medics took Lancaster to Harborview Medical Center, but he was pronounced dead at 8:25 p.m.

The next day, a detective reviewed surveillance footage of the shooting scene. She wrote in the probable cause report that Lancaster and several men were standing in the parking lot talking when a Chevrolet Impala parks nearby. Three men left the car, two of whom were later identified Marque and Jerry Fluker, reports say.

The Flukers and their passenger approached the group of men and appeared to talk for about five minutes until Lancaster and the Flukers' unidentified passenger began arguing and then physically fighting, according to court records.

The fight lasted about five more minutes, during which several people tried to intervene, including Marque Fluker, the detective wrote. However, Lancaster reportedly punched Jerry Fluker, which prompted Marque Fluker to draw a handgun from the back of his pants and shoot Lancaster several times from about five feet away, probable cause reports say.

The brothers and their passenger left the scene in the Impala.

Lancaster's autopsy examination revealed about 16 different wounds on his hand, arm, legs, chest, torso and back that were caused by gunfire. The examination determined that he was shot at least eight times.

The Flukers turned themselves in Monday after King County and Seattle SWAT teams tried to arrest Marque Fluker at his parents' apartment.

Marque Fluker remains held on $2 million bail, while Jerry Fluker is detained on $500,000 bail.
